The Sea-HP007 is your best choice for colder conditions. If a little extra
support would make hiking more comfortable then these are the hikers
to choose. The elasticised back has a wide covering band which can be
pulled in from both sides and Velcro locked to give support. You can
quickly adjust
to suit the level of support you want and to customise the fit and feel
around the waist and back. This is a positive locking system so no braces
required and allows maximum upper body movement. This is a fixed batten
suit.
